Like any low-dropout regulator, the external capacitors must. The temperature stability of Tantalums is typically very good.

Dropout Voltage Note 7. Output adjusts from 1. Dropout voltage is defined as the input to output differential datasheeet which the output voltage drops mV below the value measured with a 1V differential. Zulkim It is also important that the turn-on and turn-off voltage sig. F is required the amount of capacitance may be in.

Schottky diode see below must be used in applications. The internal diode can also be turned on if the input voltage. Ultra low dropout voltage.
